build: ensure C++14 is selected

The expectation is that --enable-libsdbusplus is default, but the
configure script had it default in some conditions and not default
in others.  As a result, if you left off --enable-libsdbusplus, C++14
support was not enabled.

Fix this by making sure all conditions based on configure flags use
the same logic rather then checking against 'yes' in some cases and
'no' in others.
